The mean captures total spending per purchase, while the median identifies the midpoint of a sorted price distribution. Here is how to calculate both and decide which better represents a market.
Stacked area charts show how a total and its composition change over time, but moving baselines make most individual categories difficult to compare precisely.
Use a pie chart for a small, clearly differentiated composition of one meaningful whole. Use a bar chart when readers need to compare, rank, or distinguish similar values.
A confidence interval describes uncertainty about an average, expected value, or parameter. A prediction interval describes uncertainty around a new individual outcome—and is usually much wider.
A survey’s margin of error describes sampling uncertainty, not total accuracy. Here is how to evaluate the errors and design choices hidden behind the ± figure.
Downloads measure acquisition activity, while active-user metrics measure qualifying use during a defined period. Here is how to compare them without confusing installs, devices, accounts, and people.
Cloud cost per user becomes useful only when the cost scope, user denominator, allocation method, and workload drivers are clearly defined. Here is a practical SaaS framework.
Revenue share measures a company’s share of market spending, while unit share measures its share of comparable volume. Price, product mix, channels, geography, and timing can make the two measures produce very different competitive rankings.
A benchmark score measures performance under particular tasks and settings. Compare models by documenting the full evaluation, quantifying uncertainty, and validating results on your workload.
NPS compresses willingness-to-recommend ratings into one accessible number, but the score can conceal composition, sampling, uncertainty, and context differences.
